The "69" position is where one lover lies head to tail over the other and each gives the other simultaneous oral stimulation.

Oral stimulation in this position will work comfortably if her mouth is large enough for his penis and if he doesn't thrust violently.

Totally engorging the erect penis in her mouth she presses and caresses his testicles, allowing her saliva to flow over them.

Pressing the cheeks of her buttocks apart, the man is able to caress the widely opened lips of her vulva with the tip of his tongue at his pleasure, likewise titillating her anus with his tongue. He could also stimulate her clitoris.

If you are a couple who enjoy licking and probing the genitals with the tongue, then this can be a tremendously exciting route to simultaneous orgasm.

Sixty-nine or 69, also known by its French name soixante-neuf (69), is a group of sex positions in which two people align themselves so that each person's mouth is near the other's genitals, simultaneously performing oral sex. The participants are thus mutually inverted like the numerals 6 and 9 in the number 69, hence the name. This position can involve any combination of sexes. A 69 can also be performed with both partners on their sides, perhaps a more relaxed position.

Variations of the 69 positions include mutual anilingus or "double rimming," and digital penetration of either partner's anus or vagina.

In these positions, the partners are said to experience sexual stimulation simultaneously, but this can also distract those who try to focus solely on pleasuring themselves. The position can also be awkward for partners who are not similar in height.
